Question about USAMO, self esteem, and college
xHypotenuse   25
N an hour ago by anticodon
Hello everyone. I know this question may sound ridiculous/neagtive but I really want to know how the rest of the community thinks on this issue. Please excuse this yap session and feel free to ignore this post if it doesn't make sense, I don't think I really have a sane mind these days and something has gotten into my head.

I want your advice on what I should do in this situation. It has been my dream to make usamo since ~second semester of 9th grade and I started grinding from that time on. Last year, I qualified for the aime and got a 5. This year I really wanted to qualify for the olympiad and studied really hard. I spent my entire summer working on counting and probability, the subject I suck at the most. And yet, on amc 12, I fumbled hard. I usually mocked ~120-130s on amc 10s but on amc 12 this year, I got really mediocre scores ~100. So I had no chance of making usamo.

So during winter of 2024-2025 I kinda gave up on aime studying and I was like "hey, if I can't get into usamo, maybe ill qualify for usapho." Since I was pretty good at physics at that time. So I spended my winter hard grinding for f=ma and guess what? The test had stupid and ridiculous questions and I only got an 11. What really sucks is that even with the stupid amount of cheaters in f=ma, if I changed all of my "D" guesses to "C," then I would have qualified. Since I solved 10 actually and guessed the rest. Absolutely unfair that only 1 of my guesses were correct.

And also since I didn't study for aime, I ended up being super rusty and so I only got a 7. Solved 9 tho. (I usually can consistently solve 10+ on aimes).

And now here's my senior year and ofc I want to apply to a prestigious college. But it feels stupid that I don't have any usamo or usapho titles like the people I know do. I think I will have good essays primarily due to a varied amount of life experiences but like, I don't feel like I will contribute much to the college without being some prestigious olympiad qualifier. So this led to me having a self esteem issue.

This also led me to the question: should I study one last year so that I can get into usamo in my senior year, or is there no point? Since like, colleges don't care about whatever the hell you do in your senior year, and also, it seems just 'weird' to be grinding math contests while the rest of the people from my school are playing around, etc. So this time around I've really been having an internal crisis between my self esteem (since getting into usamo will raise my self esteem a lot) and college/senior choices.

I know this may seem like a dumb question to some and you are free to completely ignore the post. That's fine. I just really want advice for what I should do in this situation and it would really help bring my life quality up

Thanks,
hypotenuse

2014 Triple Mock AIME [Mock AIME III released]

N Jan 7, 2024 by parmenides51
Source: Mock AIME III due on Tuesday, March 11
Welcome to the 2014 Triple Mock AIME!

This is a series of three mock AIME's written by mcdonalds106_7, fractals, and Iggy Iguana, and proofread by ksun48. This is a project we have worked on since last February, and we are excited to announce that the first test will come out in about a week. For each test, you will have about one and a half weeks to complete.

Rules

Each test will have a submission form that requires an AoPS username to complete it. Still, you should sign up in this thread (And hide the list of participants), so we have a general idea of how many people are going to take the test.

Mock AIME I here.

Mock AIME II here.

Mock AIME III here.

There we go, solutions are done for the second AIME, just in time for the real one.

As a bonus, I figured out #8 and #14 on the first AIME, so the document is updated with that.

Edit: I just figured out #10 on the third AIME and now, #13 on the first AIME.

2 months late, but I managed to figure out all of the problems on all three AIMEs, so the solution manuals are all done.

Answer Key for Mock AIME III

Take the above answer key with a grain of salt though because one was never released by the problem writing group and I may have made a mistake in my solutions. I have checked them over so I don't think they should be wrong.

Also, these three tests may have been much harder than a normal AIME, but the problems are great, and I encourage anyone who is grinding for AIME to use these as practice.
